Hi,

I have FC5 installed on my system, I want to tweak something in my
initrd.img file,
The problem is how do i acces the filesystem on the initrd.img,

I remmember having been able to access initrd.img on debian and knoppix
systems,
what did was -
i uncompressed the initrd.img
then simply mounted it into a temporary directory -
mount initrd_uncompressed.img /mnt/temp -o loop -t ext3 (or ext2)

but it just doesnt work on fc5 !, it says bad superblock error and all

bye,

Starting with (I think) FC3 (but maybe FC2), Fedora initrd images are
compressed cpio archives.

Thanks ! that worked ..
but one thing, that took lot of my time -
cpio by default compresses files into an 'old binary format'
however initrd images nedded by fc5 kernels are compresses using the
'newc' format

that means you can incompresses the initrd , modify it, then
recompress,
but if you do not explicitly mention the 'newc' format duing
compression , the kernel will hang after loading itself and not budge
any further.---

(no! no! ) find | cpio --create > /boot/initrd_new.img (Wont ! work !)
find | cpio --create --format=newc > /boot/initrd_new.img (Will work
!)
